The Tribune Tower (photo) opened to rave reviews in 1925. The statue of Nathan Hale still greets people, as do the carved images of Robin Hood (representing the architect Hood) and a howling dog (representing the architect Howells) above the entrance. Also, parts of important historical sites (brought back to Chicago by Tribune correspondents) still grace the base of the structure, including stones from such sites as the Taj Mahal, the Parthenon, and the Palace of Westminster, petrified wood from the Redwood National and State Parks, and pieces from the Great Pyramid, The Alamo, Notre-Dame, Abraham Lincoln’s Tomb, the Great Wall of China, the Berlin Wall, and most recently, the World Trade Center in New York.
